GSM based three phase motor controller program problem

[sribangaram]

Dear Friends i need small modification for my program this program working fine but i wont to add 3 phase detection when any phase will be fail or avail then send to sms and at the same time if motor in HIGH position immediately change to LOW position

const int analogPin1 = PIN_A0;   // pin that the eb L1 sense
const int analogPin2 = PIN_A1;   // pin that the eb L2 sense 
const int analogPin3 = PIN_A2;   // pin that the eb L3 sense
const int analogPin3 = PIN_A3;   // pin that the dry run sense
const int threshold = 1023;   // an arbitrary threshold level that's in the range of the analog input

int repeat = 0;
int LED = 8;
int motor = 9;
int buttonpushcounter =0;
int buttonstate =0;
int lastbuttonstate =0;
int temp=0;
int i=0;

  // read the value of the potentiometer:
